CUSHION-TIRE.

To all whom t may concern: Y

Be it known that I, JOHN C. Busoni), a citizen of the United States, and a resident o1" Highland Fark, in the county of'Wayne and State of Michigan, have invented certain new and useful Improvements in Gush? ion'lires, of which the following is a speciiication. i

My inventionV is an improvement in cush ion tires, and has for its object to provide a tire of the character specified, having thev Fig. 4 is a perspective vlew .of one of the.

tread block holders. y

In the present embodiment of the invention, the improved tire is shown in connection with a wheel consistingor` the usual hub 1, the felly 2, and the spokes 3 connecting the hub and the telly.

A housing rim is arranged on the felly 2, the said rim being an annular channel shaped casing consisting of a bottom 4 which rests upon the peripheral surface of the elly, and side walls 5 which extend radially from the bottom. A series of annular flat seamless springs 6, 7 and 8 is arranged coaxially with the wheel, within the channel shaped casing, v

Bolts 9 extend between the side walls 5 of the channel shaped casing at suitable intervals, between the springs 6 and 7, and these bolts are engaged by nuts 10 on the outer face of the casingside wall. Connecting and spacing blocks 11a are arranged between the spring 6 and the bottom 4 of the rim, and similar blocks 11 are-arranged between the springs 6 and 7, the latter series'of blocks being held by the bolts 9 before mentioned, while the former series of blocks is held by similar bolts 12. The bolts 9 and 12 pass through openings in the side walls 5 ofthe rim 4 5', and through longitudinally extending openings in the spacing blocks 11 and 11 and are engaged by nuts outside of the rim. The spacing blocks 11a space the spring 6 from the bottom of the rim, while Specification of Letters Patent. Patented Feb. V22, 1921.

the spacing blocks 11 space the spring 7 from the spring 6, that is, (the spacing blocks properly space the springs 6 and 7.

Referring to Fig. 2, it will be seen that each spring 6 and 7 is supported by a series of spacing blocks, and that the outer faces of the blocks "are rounded transversely so that the springs may berocked thereon.

These blocks are bored longitudinally to receive the bolts, and they are arranged at suitable intervals about the circumference of the wheel. The holders for the tread plates one of which is shown particularly in Fig. 4,

' are plates 13, which have inwardly turned flanges 14 underlying the inner face of the plates in spaced relation, and the spring 8 is received between these flanges 14 and the body of the plate. Thus the holders are lieldon the spring 8.

Each Vholder has at its ends outstanding flanges o r ribs 15, and each of these ribs has an inwardlyoifset portion 16 at its free edge. Each holder is also provided with a threaded opening at its center and with an enlargement 17 at the opening forming a reinforcement for the opening.

The tread blocks 18 are of resilient material, as for instance, rubber, and each block seats upon a holder, resting upon the body 13 thereof between the flanges 16, and the ends of the blocks as shown more particularly in Fig. 2 are recessed transversely as shown at 19 toreceive the inwardly offset portion 16 of the flanges 15.

The inner surfaces of these blocks are also grooved transversely as shown in Fig. 2, to increase resiliency. Each of the side walls 5 of the channel shaped casing has an inwardly extending lip 2O at its outer edge, and these lips engage in rabbets 21 at the sides of the block. The rabbets extend from the outer face of the block, and the lips preventoutward movement of the blocks by engaging in the rabbets, and also prevent lateral movement of the blocks. Y

' Each block is held to the adjacent Yholder by means of a screw 22 which passes through the block and engages the threaded opening of the holder. The heads of these screws are counter-sunk in recesses 23 in the blocks as clearly shown in Fig. 3.

Substantially channel shaped or U-shaped pressure members are arranged at alternate tread yblock holders. Two series of these members are provided, a series 24, and a series 25, and the members of the series are alternately arranged. The members ofthe Vseries 24 have inwardly extending flanges or lips 26 at their ends, which extend radially which the ends vof the spacing blocks 11 engage, and the bolts 9. pass' through these openings. f j

The flanges of the members of both series are connected by cross plates 29, the said cross plates being near the ends of the pressure members. These cross plates 'engage openings in the anges, and may be upset to prevent disengagement. The cross plates 29 rest upon the springs 6 and 7, the cross plates of the pressure members 24 resting on the spring 6, while those of the serie-s 25Y rest upon the spring 7. Thus the alternate Vtread blocks are supported by the springs Gaudi', half of theV alternate blocks being supported by the spring .6 and the other half ofthe alternate blocks being supported by Vthe'spring 7. The improved tire, may be manufactured at a very low eost,iand is not subject to the injury that may put a'pneumatic tire out of commission, such as punc tures, blow-outs, and the like. .The tread blocks are easily removed when desired, and the'entire tire may be easily assembled.
